大洋钻探与冲绳海槽

在多次赴冲绳海槽地球物理调查的基础上，综合国内外的调查研究成果，对冲绳海槽地质构造学研究的历史、已查明了地球物理场特征，海底构造特征和需要进一步探讨了问题作了系统的总结，阐明了ＯＤＰ在冲绳海槽钻探的重要意义。

ODP AND THE OKINAWA TROUGH

The Okinawa Trough which develops at the east part of the East China sea is a active rifting basin and has a series of typical geological and geophysical features as a active modern rifting valley,such as well-developed rift graben,very high heat-flow values and abundant thermal fluid activity,strong crust extension,frequent volcanic and earthquake activity,and a lot of submarine extensional faults. But up to now,there have been many scientific problems which need deep drilling data to be finally solved .ODP's drilling in the Okinawa Trough is of great scientific significance for China.
